'12 Claims. 01. 101-4151) This invention relates to new and usefulimprovements in drums for holding flexible typeholding chases.

It is one of the principal objects of my invention to provide a circulardrum composed of sheet metal stampings assembled to form a light, rigidand economical form at low cost.

It is another object of my invention to provide on my improved circularform, simple means for securely attaching flexible type-holding chasesto its outer contour.

Other important and incidental objects of my invention will be set forthin the following specification and subjoined claims.

In the accompanying drawing illustrating my invention, Figure 1 is anend view of my new circular form. Figure 2 is a longitudinal section onthe line 2-2 of Figure 1. Figure 3 is across-sectional view taken on theline 3-3 of Figure 2.

Figure 4 is an end view of one of the flexible type chases to be appliedto my circular form. Figure 5 is a plan view of one end of one of theflexible type chases, showing the formed ends of the bands. And Figure 6shows several of the chases assembled on the bands.

Referring to the accompanying drawing for a detailed description of myinvention therein illustrated, the numeral 1 designates a rectangularplate bent to circular form and having attached to its inside facesemi-circular reinforcingribs 2. The ribs 2 are provided on theirperipheries with laterally formed ears 3 to receive countersunk rivets 4by which these ribs are secured to the circular plate 1, or they may bewelded thereto.

Each of the ribs 2 isconcave on its inner face, and at one side where itmeets the plate 1, is provided with a lug 5. These lugs 5 are aperturedto receive therethrough a hinge pin 6 whose outer ends, where theyextend beyond the outside ribs 2, are peened for retention in place. 7

Above the hinge pins 6, and adjacent the inside face of the plate 1,each rib 2 is apertured to receive therein a rectangular clamp bar '7whose lower face is provided with a longitudinal V- shaped groove 8.This bar '7, like thepin 6, has

its ends peened to hold it in place. i

Mounted on the hinge pin 6 adjacent each outer rib 2 are two clampfingers 9-9 held. in spaced relation by a spacer bar 10 riveted betweenits Where the fingers 9 pass beyond the plate 1, its lower edge isprovided with registering notches 11 to permit an upward travel of thefingers and to retain them in the proper lateral position to reouter endadjacent the inner face of the plate 1.

ceive 'the flexible bands to be hereinafter described. Y

Each of the fingers, between the spacer bar 10 and the hinge pin 6, isprovided with a vertically extending stop lug 12 that engages the faceof the clamp bar 7 to prevent the outer ends of the fingers fromdropping out of the notches 11 in the plate 1. Also beyond the pin 6,each finger 9 has an apertured ear 13 to receive one end of a tensionspring 14 whose other end is secured to a spring support pin 15 that,like the pin 6, extends through the ribs 2 and is riveted in place.

Each of the spacer bars 10 midway between the fingers 9-9, is threadedto receive a clamp screw 16 whose upper end is received by the groove 8in the bar 7 and has integral with its lower end a knurled head 17.These clamp screws securely lock the strap bands and assembledcomposition in place upon the drum. I

My flexible type-holding chase that is applied to the periphery of mycircular drum, comprises type channels 18 consisting of channel-shapedmembers 19 arranged back to back and spot welded together.

One end of each tube 18 is partially closed by ears 20-20 punched fromits top flanges and turned downwardlyto retain the type within thechannel.

Above the foot portions of the channel-shaped members 19 the verticalwalls are provided with slots through which flexible strap bands 22pass. (See Figures 4, 5 and 6).

Each of the bands 22 is of sufficient length to extend around the faceof the plate 1. At one end each band is provided with an elongated slot23 to receive one of the fingers 9, and at the other end, it is providedwith a hook-shaped terminal 24 to engage the edge of the plate 1. (SeeFigures 1, 4 and 5).

The type channels are free to be moved along the bands 22 to permit thegrouping or assemblingof the composition at any desired points about theperiphery of the drum; and then, with the terminal 24 engaging one'edgeof the plate, the fingers ,9-9 are depressed until their outer endsenterthe slots 23. Now, when the pressure is released, the springs 14-14 willforce the fingers 9-9 outwardly to retain the bands in place until thethumb screw 16 is tightened against the V-groove 8 to securely lock thebands and assembled composition in place.

When it is desired to remove the composition and bands, the thumb screw16 is loosened and the fingers 9-9 depressed, permitting the slottedends of the bandsto be removed from the fingers, after which the entirecomposition may be removed without destroying it.
